Amavuta 20 Amashanyarazi

UNS N08020

UNS N08020, izwi kandi ku izina rya Alloy 20 ni kimwe mu byuma bya “super” bitagira umuyonga byakozwe mu rwego rwo kurwanya ibitero bya aside, kubera iyo mpamvu, hari uburyo butandukanye bwo kubikoresha haba mu nganda zidafite ingese na nikel. Alloy 20 isa nkaho iguye hagati yicyiciro cyose kitagira umwanda na nikel, kuko kirimo ibiranga byombi; icyakora, sisitemu yo guhuriza hamwe (UNS) amaherezo iremera ko ari nikel ishingiye ku mavuta, bityo nimero ya UNS N08020.

Alloy 20 ni austenitike nikel-fer-chromium ishingiye ku mavuta yongeweho umuringa na molybdenum. Ibigize nikel bifasha muburyo bwa chloride ion hamwe no kurwanya ruswa. Kwiyongera k'umuringa na molybdenum bitanga kurwanya ibidukikije byangiza, gutobora no kwangirika. Chromium yiyongera mukurwanya ibidukikije bya okiside, nka acide nitric, na columbium (cyangwa niobium) bigabanya ingaruka zimvura ya karbide. Uburyo bwinshi bwo gusudira burashobora gukoreshwa mugihe ukorana na Alloy 20, usibye gusudira oxyacetylene. Irashobora kandi gushyuha ikoresheje imbaraga zimwe zisabwa kugirango akazi gashyushye austenitike idafite ibyuma. Kubijyanye na mashini, kurangiza bidasanzwe birashoboka ukoresheje uburyo bumwe bwo gushiraho no kwihuta gutunganyirizwa gukoreshwa kumashanyarazi ya austenitike, nka Steel 316 cyangwa 317.
